Battle Of The Sexes

This paper examines a persuasion game between two agents with one-sided asymmetric information, where the informed agent can reveal her private information prior to playing a Battle-of-the-Sexes coordination game. There is a close connection between the extent of information revelation and the possibility of coordination failure; while, in the absence of any coordination failure, there exist equilibria with full disclosure, in the presence of strategic uncertainty in coordination there exists an equilibrium with no information revelation. We provide a purification argument for the non-existence result, as well demonstrate that it is robust to several extensions, including both-sided asymmetric information and imprecise information revelation.

Robust Designs

Robust designs protect system utility in the presence of uncertainty in technical and operational outcomes. Systems-of-systems, which lack centralized managerial control, are vulnerable to strategic uncertainty from coordination failures between partially or completely independent system actors. This work assesses the suitability of a game-theoretic equilibrium selection criterion to measure system robustness to strategic uncertainty and investigates the effect of strategically robust designs on collaborative behavior. The work models interactions between agents in a thematic representation of a mobile computing technology transition using an evolutionary game theory framework. Strategic robustness and collaborative solutions are assessed over a range of conditions by varying agent payoffs. Models are constructed on small world, preferential attachment, and random graph topologies and executed in batch simulations. Results demonstrate that systems designed to reduce the impacts of coordination failure stemming from strategic uncertainty also increase the stability of the collaborative strategy by increasing the probability of collaboration by partners; a form of robustness by environment shaping that has not been previously investigated in design literature. The work also demonstrates that strategy selection follows the risk dominance equilibrium selection criterion and that changes in robustness to coordination failure can be measured with this criterion.

The Impact

This article analyzes the most current security issues for the Republic of Moldova that are part of the regional security context of Eastern Europe –the region that can be considered the epicenter of international tensions through which the„geopolitical line of fracture”passes. The geographical position of the Republic of Moldova makes this state particularly sensitive to any negative trends in theregion. Growing of international tensions creates security threats and complicates economic development. From a historical point of view, Moldova has repeatedly fallen victim by the confrontation of the great powers. Therefore, the Republic of Moldova has a vital interest in preventing a new conflict in Eastern Europe. This article is based on a number of assumptions made by changes in the European security environment, such as the „shift of weight” to the East, strategic uncertainty, increasing the role of non-state actors, the situation in eastern Ukraine, etc. Based on these assumptions, this article makes an attempt to outline the potential role of the Republic of Moldova in the Eastern European security system, taking into account the desideratum for integration of the republic into the European Union. Other relevant factors will be taken into account for shaping the role of the Republic of Moldova in the European security system, namely: the security deficit; the impact of NATO and EU security policy; the rebirth of the project to create a regional defense alliance, etc. This article will largely take into account the military aspects of security.
